Abstract

Plasmonic resonant properties of nanoparticles, nanowires and nanotubes forming heterodimensional junctions with twodimensional electron gas (2DEG) enable local resonant coupling and could be used for subwavelength imaging. The resonant plasmon frequency of a nanoparticle is tunable by varying the bias of the gate capacitively coupled to the nanoparticles. Our analyses of the plasmonic properties of nanoparticles accounting for the boundary scattering and for the carrier fluid velocity shows that the plasma oscillations in Si, GaN, and InGaAs and nanoparticles could achieve high quality factors. Single embedded nanoparticles or arrays of such nanoparticles placed into the perforated asymmetrical 2DEG or/and 2DHG structures or superlattices could be used for detection, mixing, or frequency multiplication of sub- THz, THz or IR radiation. The embedded nanoparticle arrays could be also used as active elements of THz emitters and as sub-THz, THz, or IR sensitive photodetector layers for pixelless THz to visible converters.
